摘要

Thermodynamics of Si at low concentration in Mn-Si melt was studied by measuring the equilibrium Si content in the melt in equilibrium with MnO saturated MnO-SiO2 slag.The equilibrium Si contents were determined as 1.32 and 1.78 mass％ at 1673 and 1773K,respectively.The experimental results were analyzed using the unified interaction parameter formalism and the available data for the partial enthalpy of solution of silicon in Mn-Si melt.The activity coefficient of Si at infinite dilution,Si γ°Si and the self-interaction parameters of Si in Mn-Si melt were determined as a function of temperature.Using the thermodynamic parameters determined in the present study,the Si content in Mn-Si melt in equilibrium with SiO2 saturated MnO-SiO2 slag could be also predicted,and it was in good agreement with the experimental data.
